Hi experts,

Can you share any documents describing the security features of LPC55S36JHI48 ?
Does LPC55S36JHI48 have PSA level 3 certificate ? any document stating it ?

Hi @limingzhou 

All LPC55S3x security documents are posted on the device homepage

https://www.nxp.com/products/LPC553x#myDocument

Select "Secure" option, you will see the list

LPC55S36 has PSA level 3 certificate, see declaration here

https://products.psacertified.org/products/lpc55s36

Regarding to your Q2 of boot time, The LPC55S3x supports booting from internal flash, external flash, or ISP mode, depending on configuration. the boot time information is not documented in any existing files. So I suggest you creating a private ticket to request it. Please address your project information and why this information is necessary to you in your ticket. Our support team will get back to you for it.

Thanks,

Hi Jun,

Again,

 I tried to open the documentation section on the device homepage.

 By selecting "Secure" option,  however there us nothing document available.

 Seems no access rights.

 I logged in using my NXP account,
